A wireless transmit/receive unit (WTRU) may send a discovery request to a first edge enabler server (EES) instance to obtain edge application server (EAS) information. The WTRU may receive a discovery response from the first EES instance. The discovery response may indicate a list of EAS information and/or registrar EES information for one or more EAS instances in the list of EAS information. The WTRU may select an EAS instance based on one or more of the list of EAS information or the registrar EES information for the one or more EAS instances. A second EES instance of the plurality of EES instances may be the registrar EES of the selected EAS instance.
